RF receiver ICs up battery life

SAN JOSE, Calif.  Responding to the needs of makers of remote keyless entry systems, Micrel Inc. has rolled single-chip RF receiver ICs that let OEMs extend battery life but maintain or improve system performance. The MICRF002 and MICRF022 also offer sensitivity and range about 6 dB better than that of their predecessor, the MICRF001, Micrel said.

The MICRF002BM comes in a 16-pin small-outline IC and the MICRF022BM in an eight-pin SOIC. Each costs $2.95 in 1,000-piece lots.
